Power Integrations’ SCALE-iDriver ICs carry AEC-Q100 certification for automotive

Power Integrations announced that two members of its SCALE-iDriver gate-driver IC family are now certified to AEC-Q100 Grade Level 1 for automotive use. The two parts, SID1132KQ and SID1182KQ, are suitable for driving 650 V, 750 V and 1200 V automotive IGBT and SiC-MOSFET modules, and are rated for peak currents of +/-2.5 A and +/-8 A respectively. The SID1182KQ has the highest output current of any isolated gate driver available and is capable of driving a 600 A /1200 V and 820 A /750 V switch.

The SCALE-iDriver family of single-channel IGBT and SiC-MOSFET driver ICs features Power Integrations’ innovative FluxLink magneto-inductive bi-directional communication technology which ensures reinforced galvanic isolation between the primary and secondary sides, setting a new standard in isolation integrity and stability. FluxLink technology eliminates the need for opto-electronics, which suffer parametric changes with age and relentless thermal degradation that limits operational lifetime. Use of magnetically-coupled conductors locked into a homogenous thermoset, high quality insulation greatly enhances operational stability and longevity. The devices utilize Power Integrations’ compact and robust eSOP package, which offers a CTI level of 600, 9.5 mm creepage and clearance distance, and easily meets automotive 5500 m requirements.

SCALE-iDriver devices minimize the number of external components required, simplifying the BOM and permitting two-layer PCB layouts, which reduces interference and increases the reliability of the whole system. The automotive DC-DC converter for the secondary-side supply voltage is greatly simplified as only a unipolar voltage is required by the SCALE-iDriver IC. Built-in voltage and power management circuitry handles the necessary regulation of positive and negative gate-drive voltages. The IC features a full range of safety features including Advanced Soft Shut Down (ASSD) for short-circuit turn-off and under-voltage protection. SCALE-iDriver ICs are available now, priced at $4.12 in 10,000 quantities.
